RAM overclock - necessary for CPU overlock?

[l0G0tYP3]

Today i've had some problems with my overclocking. My RAM clock has reached it's highest clock frequency while my CPU can be overclocked further.

So can I lower the multiple of the RAM without causing any problems?

Do the RAM have to run at a certain speed for a CPU to work properly?

Yes, if your BIOS has a RAM divider or equivalent settings to change the target frequency of the RAM to operate within its specifications.

Do the RAM have to run at a certain speed for a CPU to work properly?
They have to be stable, generally that means they should pass the memtest86+ tests at boot from POST @their operating frequency.

see above

It is possible that you could raise the voltage for the RAM and loosen the timings to get a little more MHz out of the RAM too.

Why don't you list what CPU/Motherboard/RAM you have and list the overclock settings you currently use (like voltage, timings, MHz, FSB, etc...)

There's a good chance that your RAM overclock is limiting the CPU overclock.

Need specs.

i don't think he's asking what you guys are answering. i think he's just saying his rated RAM speed is hit, can he go further?

it depends on what type of RAM you have, but most RAM can be overclocked. if you have 2 cores and your FSB is 400mhz, and your RAM is 800mhz, then you are hitting your stock clock RAM speed. in my case i have my FSB at 425mhz, while the RAM is rated at 800mhz, but now is running at 425mhzx2=850mhz. it runs fine and could go further if i wanted to OC my CPU further.

so, you should be fine. i would just make sure you change the timings on your RAM to whatever they should be (i.e. 5-5-5-15, etc.). a lot of times if you change the clock speed, your BIOS will automatically change their timings, and this will inevitably lead to a BSOD of some type.

if you're really concerned about upping the RAM mhz, take off your case cover and touch the RAM every half hour while you run a stress test like p95. if you can leave your finger on it for 10 seconds, your RAM is fine (assuming you aren't failing stress tests). btw, run the blend test in p95 so it uses your RAM.

Ok, so what you posted above is basically equal to my post from before "It is possible that you could raise the voltage for the RAM and loosen the timings to get a little more MHz out of the RAM too."

no it isn't...i don't think he is saying he CAN'T get more mhz out of the RAM, just asking if it's okay to do it. you're assuming he has hit a wall, and i think he just wants to know if it's okay to keep going. i could be wrong though...that's just how i read it.
